California Megan's Law Website
Search for Ontario sex offenders at meganslaw.ca.gov. This is the official California sex offender registry. You can search by address, zip code, or name. Enter an Ontario address to see offenders living nearby. The map tool shows pins for each registered person. Click a pin to view their profile.
Each profile includes a photo, physical description, date of birth, and verified address. The site lists the crimes that led to registration. Most profiles show the person's registration tier. Tier One offenders register for at least ten years. Tier Two offenders register for at least twenty years. Tier Three offenders register for life.
Some offenders are excluded from the public website by court order. These people still register with local police, but their information does not appear online. The law protects certain juvenile offenders and some low-level misdemeanor offenders from public disclosure.
Before you search, you must accept a disclaimer. The site warns that misusing registry information is a crime. Do not use the data to harass or harm an offender or their family. Penalties include fines up to $50,000 and five years in prison for felony misuse. Anyone who uses the data to commit a misdemeanor faces fines between $10,000 and $50,000.
Registered sex offenders are not allowed to use the search function. Anyone required to register who accesses the tool faces a fine of up to $1,000 and up to six months in jail. The law aims to prevent offenders from using the system to locate other registrants or potential victims.
Compliance Monitoring
Ontario police conduct compliance checks on registered sex offenders. Officers visit the addresses offenders have reported to verify they live there. These checks help keep the registry accurate. If an offender moves without updating their registration, police can issue a warrant. Registration violations are prosecuted as felonies or misdemeanors depending on the circumstances.
Some offenders wear GPS ankle monitors. California requires all sex offender parolees to be tracked with electronic devices. The CDCR Sex Offender Management Program has used GPS monitoring since 2008. The system alerts parole agents if the person enters a restricted area like a school or park.
California Registration Laws
California Penal Code Section 290 requires sex offender registration. This statute lists all crimes that trigger a registration requirement. Examples include rape, lewd acts with minors, sexual battery, indecent exposure, and possession of child pornography. The law also covers attempts and conspiracies to commit these offenses.
The three-tier system took effect on January 1, 2021. Senate Bill 384 created this tiered approach. Before that date, most sex offenders registered for life. Now they are divided into three tiers based on the severity of their crime. Lower-level offenses like misdemeanor sexual battery fall into Tier One with a minimum of ten years. Mid-level crimes like lewdness with a minor under 14 are Tier Two with a minimum of twenty years. Serious offenses like rape are Tier Three with lifetime registration.
Offenders in Tier One or Tier Two can petition the court to end registration after the minimum period. The court has 60 days to respond. If the petition is granted, the person is removed from the public website and no longer has to register. Tier Three offenders cannot petition. They register for life unless they receive a pardon or other legal remedy.
Penal Code Section 290.012 sets update requirements. Most offenders update once per year within five working days of their birthday. Sexually violent predators update every 90 days. Transients with no permanent address update every 30 days. The law says no entity may charge fees for registration.
Penal Code Section 290.46 mandates internet disclosure through the Megan's Law website. The California Department of Justice publishes information on most registered sex offenders. The statute specifies what data can be disclosed, including name, photo, address, and conviction details.
